Patent CA-2388469-A1 (CA)
Inventor: WANG SHAOTIAN
IPC: B01J31/14
Filed: 2000-09-11
Abstract: A single-site olefin polymerization catalyst is described. The catalyst comprises an activator and an organometallic compound that includes a Group 3 to 10 transition or lanthanide metal, M, and a modified boraaryl ligand. We surprisingly found that the catalyst is more active in olefin polymerization compared to other catalysts containing non-modified boraaryl ligands. Most surprisingly, the supported catalyst gives polyolefins with a multimodal molecular weight distribution having separate components of distinct molecular weight.

Title: Concentrated aqueous bromine solutions and their preparation
Inventor: MOORE ROBERT M JR
IPC: A01N25/02
Filed: 2000-11-06
Abstract: A concentrated liquid biocide composition is produced by a continuous proces s. The process comprises continuously feeding into mixing apparatus (i) bromine  chloride and (ii) an aqueous solution of alkali metal salt of sulfamic acid.  These are proportioned to produce an aqueous product having an active bromin e content of at least 100,000 ppm (wt/wt), and an atom ratio of nitrogen to active bromine from (i) and (ii) greater than 0.93:1. The desired product which is thus continuously formed, is withdrawn from the mixing apparatus at  a rate sufficient to enable the continuous feeding to be maintained. Thus, the  withdrawal of the product can be continuous or intermittent, depending upon the type of mixing apparatus being used. In various embodiments of the invention, the bromine chloride is continuously produced from separate feed streams of bromine and chlorine by maintaining such streams under automatic feed rate control whereby the streams are continuously proportioned to come together to form bromine chloride.

IPC: B64C13/00
Filed: 2000-12-14
Abstract: Methods and systems for fail-safe process execution, monitoring and output control for critical systems operating on an open bus architecture with multiple, independent partitions on a single processor is presented. The control system state variables and their status of critical systems, within the control laws and mode logic, are monitored for process completion and health, and shut down if necessary. The embodiments provide for a dual path for shut down of, for example, flight critical systems so that the failure of one partitioned module does not affect the operation of the remaining partitioned modules. One path involves the CPM (10) and IOC (20) determination of command/response health. If persistent faults are detected, then either the DSP (30) monitoring or the CPM performance monitoring results in a discrete signal being sent to the H-bridge (40) disable (403) to shutdown the current output. The second path is CPM controlled via a separate discrete signal on the input/output controller (20) to the flight critical system shut-off valve (60). By implementing these separate paths, critical systems in one partition cannot be defeated by a single failure in another partition (102).

Title: Organizing and combining a hierarchy of configuration parameters to produce an entity profile for an entity associated with a communications network
Inventor: PETRIE DANIEL G
IPC: H04M1/247
Filed: 2001-03-20
Abstract: A method of and system for organizing a hierarchy of sets of one or more parameters, for example, configuration parameters, maintaining the plurality of parameter sets, and combining two or more of the plurality of parameter sets to produce a single set of configuration parameters (i.e., an entity profile) for an entity, where such entity may be associated with a communications network. The generated entity profile may be used to configure a device, for example, a network device, associated with the entity. Provided is a digital information product, comprising a computer-readable medium; and first signals tangibly-embodied on the computer-readable medium. The signals define, for an entity associated with a communications network and that belongs to one or more entity groups of a hierarchy of entity groups, a plurality of sets of configuration parameters for configuring a network device of the communications network. Each set corresponds to either the entity or one of the entity groups and, for each set, for one or more configuration parameters, the set defines a value for the configuration parameter. Further provided are a method of and system for assigning values to one or more configuration parameters of a first entity associated with a communications network. The entity is a member of a hierarchy of entity groups, and the communications network comprises a computer-readable medium. A plurality of sets of configuration parameters for configuring a network device of the communications network are retrieved from the computer-readable medium, where each set corresponds to either the entity or one of the entity groups. For each set, for one or more configuration parameters, the set defines a value for the configuration parameter. The plurality of sets of configuration parameters are combined to produce an entity profile for the first entity, where the entity profile comprises one or more configuration parameters and comprises, for each parameter, a corresponding value assigned from one of the plurality of sets of configuration parameters.
Patent CA-2408200-A1 (CA)
Inventor: RICHTER RAY C
IPC: H01R11/22
Filed: 2002-10-15
Abstract: The invention makes use of a spring tensioned electrically non-conductive clamp with electrically conductive gripping teeth, electronic circuitry housed within the clamp body, electrically conductive wires protruding from the rearward end, and externally visible indicator light sources mounted within the clamp. The invention is used to monitor current flow through said tips, and within the rearward-connected wires, and to provide static bonding. When a current flow has been established between the said tips or rearward exiting wires, the electronic circuit will extinguish as indicator light source for each of the monitored current flows. When the conductive tips are electrically bonded to a conductive material, static bonding will exist between a centrally removed connection point via the exiting rear wires and the conductive material placed between the said teeth, when this condition occurs all indicating light sources will be extinguished and hence the electronic circuitry will be in a near-off state.

The apparatus includes an inlet pipe into the vessel at a position below the settled level of particles, and a pump which recirculates liquid from the vessel above the submerged level of particles, remote from the settled level of particles, and a static pressure instrument connected to the inlet pipe. A solids pump can be activated to remove settled particles from the vessel, the operation of the pump being controlled by the measured level of settled particles.

IPC: H04L29/06
Filed: 2003-03-17
Abstract: A network includes a server 1 and a number of clients 2, which will in operation of the network require authentication by the server 1. The server 1 distributes authentication information to other clients 3 when a session is initialised. When the server 1 needs to authenticate a client 2, it hands out a server request to the client 2 which asks client 2 for authentication information which it must obtain from other clients 3. The client to be authenticated 2 then sends these requests to the clients 3 specified in the authentication request to obtain the authentication information from those clients. Once the client to be authenticated 2 has received the relevant authentication information from the other clients 3, it returns it to the server 1 and is authenticated or not accordingly.

Inventor: LEE HAN-SEN
IPC: B27M1/00
Filed: 2002-01-30
Abstract: The structures and process for producing the structures of the invention enable extensive and efficient use of block scrap for slat manufacturing. The techniques employed advantageously accomplish two goals simultaneously, enabling scrap, such as block scrap, to be formed into longer effective lengths. Such longer effective lengths can then be cutably formed into slats of various sizes. The join of the block scrap is by deeply extending, finite interlock length finger joints which, once the material is cutably formed into slats, remain as relatively shallow and finite interlock length finger joints. The joints have the added benefit that they statistically "break up" any grain differences which would otherwise create warp, and enable long lengths of slat to be employed from several shorter lengths of scrap. An applied covering layer may be applied by wrapping or insertion. An ultraviolet resistant lacquer may be applied to the covering layer for long window life and attractive finish.
